Objectives and Applications
The SCISAT satellite has been in continuous spaceflight operation since 2003. It now measures over sixty (60) atmospheric species at still one of the world’s highest vertical resolutions possible, and includes ozone, ozone depleting substances, all major greenhouse gases, and HFCs. Many of these species are measured by no other instrument or satellite world-wide, making Canada the sole provider of these datasets globally. As of 2024, the objectives of the mission remain to broadly assist in monitoring the UN Montreal Protocol, the Kigali Amendment, the Paris Climate Agreement, and the Canadian Environmental Protection Act. Specific objectives include to assess the quality of model predictions for: EC’s UV forecasting system, atmospheric carbon transport, and climate-chemistry process studies.
